Graceful White Dress in Dramatic Chiaroscuro Lighting

A woman in a flowing white dress poses gracefully on a glossy black floor. Cinematic, high-contrast lighting (chiaroscuro): a single hard spotlight from the upper left casts dramatic shadows, creating a luminous rim around her silhouette. She stands with one hand on her hip and the other raised softly, head tilted slightly, exuding elegance and poise. The dress catches the light with subtle silk sheen and refined folds. The background is a deep charcoal gradient with faint smoke and floating dust, adding atmosphere. Perspective is slightly low, using a 50mm lens, shallow depth of field, ultra-realistic texture, rich detail in fabric, warm golden highlights on the dress against the cool dark floor. Mood: timeless, mysterious, graceful.
